3 Claims. (Cl. 30-124) This invention relates to a holding device, moreparticularly to a wire holding and adjustable tensioning device, and isa continuation-in-part of L. G. Spencer US. application Serial No.604,865, filed August 20, 1956.

Present methods, involved in the attaching of wires to fixed terminalsof a piece of apparatus, are awkward since the operator must hold thewires, mechanically attached to a terminal with a predeterminedtensional force, as well as the solder, with one hand, leaving the otherhand to hold the soldering iron.

An object of this invention is to provide a wire holding device wornupon a finger of an operators hand leaving the operators handsunconstrained.

Another object of this invention is to provide a wire holding devicewith the foregoing characteristic having means to adjust the tension ofwires which are mechanically attached to terminals of a piece ofapparatus.

A further object of this invention is to provide a wire holding devicewith the foregoing characteristics having means to release the wiresfrom the holding device.

Another object of this invention is to provide a wire holding devicewith the foregoing characteristics having means to adjust the length ofthe wire between the wire holding device and the terminals of a piece ofapparatus.

A still further object of this invention is to provide a wire holdingdevice with the foregoing characteristics having means to sever apredetermined length of the wire extending from the terminals of a pieceof apparatus in which the wire is attached.

These and other objects are obtained by providing a finger ring having amounting means projecting therefrom on which is superposed a pair ofplate-like jaws arranged to grip an elongated object between theircooperating edge faces, one of the jaws being fixed to the mountingmeans and the other jaw being pivoted to provide eccentric co-actionbetween the co-operating faces, the pivoted jaw being spring-tensioned apredetermined amount to urge it into the gripping position with thestationary jaw.

A better understanding of the invention may be obtained by referring tothe following description, taken in conjunction with the accompanyingdrawings in which like numbers refer to like parts, in which:

Fig. 1 is a perspective view showing the use of the invention;

Fig. 2 is an enlarged perspective view of the wire holding device inwhich the invention is represented;

Figs. 3 and 4 are views showing in elevation the gripping jaws, formingpart of the invention, in the gripping and released positionsrespectively;

Fig. 5 is a sectional view taken at 5--5 in the direction of the arrowsFig. 4; and

Fig. 6 is a view of the jaws employed in the invention.

Referring to the drawings, there is illustrated a finger ring 1 adaptedto mount on the finger 2 of a person, the ring 1 being formed of anysuitable material and having an end 3 overlapping the end 4 which allowsthe 2 ring to fit any size of finger by reducing or enlarging thecircumference of the ring by the application of pressure thereto.

Projecting from the ring 1 is the gripping means, mounted on the bracket5, comprising a stationary grooved jaw 6 secured to bracket 5 and havinga rear ing insertion and removal of the wires, and a movable undercutjaw 8 pivoted by pin 9 on bracket 5, tensioned into gripping engagementwith jaw 6 by spring 10, one extremity of this spring being attached tobracket 5 by stationary pin 11 and the other extremity to jaw 8 by pin12, and having a lug 13 with a cutting edge 13 at its outer extremity.The curvatures of the co-operating edge faces 14 and 15 by jaws 6 and 8,respectively are circular in configuration having a center of curvatureat C and radius R, Fig. 4. Jaw 8 however is pivoted eccentrically by pin9, the pivot point thereat being spaced a predetermined distance apartfrom the center of curvature C of the circular edge face 15. Thedistances from the pivot point at pin 9 to a succession of points onedge face 15 increase in a clockwise direction and decrease in acounter-clockwise direction. Therefore as jaw 8 is rotated in aclockwise or counter-clockwise direction, the spacing between the edgefaces 14 and 15 increases or decreases respectively. Any other method ofperforming this function may be used.

Associated with the gripping means are the wires 16, 17, contained onthe supply reels 18, 19, respectively, for attachment to the terminals20, 21 respectively, mounted on a piece of apparatus 22. A solderingmaterial 23 is held in one hand of the operator while a soldering iron24 is held in the other hand.

In the operation of the device, the movable undercut jaw 8, of the jaws6 and 8 which are shown in the clamped position in Fig. 3, is rotated byhand clockwise so that the edge faces 14, 15 of the jaws 6 and 8 arespaced apart as shown in Fig. 4. The wires 16, 17 are then inserted inthis separation and the movable grooved jaw 8 allowed to return, byvirtue of spring 10, to the position where the wires 16 and 17 aregripped by the jaws 6 and 8 as shown in Fig. 3.

The operator by slightly twisting his hand, on which the holding deviceis mounted, and drawing that hand towards himself a predeterminedamount, causes the jaw 8 to ride on the wires 16, 17 so that the jaw 8rotates clockwise sufiiciently to allow the lengths of the wires 16, 17,between the ring 1 and the terminals 20, 21, to be adjusted. By holdingthe hand, on which the holding device is mounted, so that the wires 16,17 are just taut, they will remain gripped by jaws 6, 8 by virtue of theaction of spring 10 in order that the soldering operation may be carriedout.

Upon the completion of the soldering operation, the operator suddenlydraws his hand, on which the device is mounted, towards himselfmaintaining the wires 16, 17 in contact with jaw 8 causing jaw 8 torotate clockwise since wires 16, 17 ride thereon, allowing the cuttingedge 13' to sever wires 16, 17.

What is claimed is:

1. A wire holding device comprising in combination: a finger ring;mounting means projecting therefrom; a pair of oppositely disposedplate-like jaws, their cooperating edge faces being circular inconfiguration, spaced apart so as to grip an object between thecooperating edge faces, one of the jaws being fixed on the mountingmeans and having its edge face grooved, the other jaw being undercut,pivoted on the mounting means so that its axis of rotation is eccentricto the center of curvature of its co-operation edge face to provideeccentric co-action between the co-operating edge faces when the pivotedjaw is rotated in a clockwise or counter- 3 I 4 a clockwise direction;resilient means attached to the of the pivoted jaw, having a cuttingedge projecting pivoted jaw and to the mounting means and arranged toagainst the co-operating face of the stationary jaw when urge theco-operating edge face of the pivoted jaw into the pivoted jaw isrotated in a clockwise direction. gripping-relation with thecoroperatingnedge face hot the fixed jaw. h M d d th 1 1 5 ReferencesCited in the file of this patent 2. wire 0' ing cvice in accor ance wi.c aim in which the diameterof the'said ring is adjustable.
